I recently had a PC semi-custom built after an attempt to upgrade my power supply unit and graphics card went sour (stupid HP case and motherboard were too small). I now have a case designed for gaming with four fans, a new motherboard, a 600W power supply unit, a GeForce GTX 460 and 8 gigs of RAM. My Processor is an AMD Athlon(TM) II X4 620 (3 CPUs) ~2.6 GHz (I kept the processor from my old PC).
Theoretically, the game should be running great, right? However, after reinstalling it and copying over my downloads/the Awesomemod framework/etc., I'm finding the game basically unplayable. It freezes constantly, just for a few seconds, but it's annoying and happens most often when I try to zoom in or out, move the camera, switch between characters or choose an action. When I opened taskmaster, I noticed the CPU is jumping between very low and 100% usage. It only does this when Sims 3 is running- it hasn't happened when I play other computer games like Dragon Age 2, surf the internet or watch videos.
Is there something I'm doing wrong? What can I do to make my game run more smoothly- or at least be playable without constant freezing?
I'd check to make sure you don't have any corrupt CC.
